Privacy Policy

Last updated: July 2026

What this site does

Biochemtools provides free calculators and interactive explainers. All calculations run in your browser — the numbers you type into a tool are never sent to or stored on any server.

No account, no personal data collection

There is no signup and no login. This site does not ask for your name, email, or any personal information to use any tool, and does not store the inputs or results you generate.

Cookies and analytics

This site may use privacy-focused, aggregate analytics (such as page-view counts) to understand which tools are useful and improve the site. This does not identify individual visitors.

Advertising

This site may display ads served by third-party advertising networks (such as Google AdSense) to support free access to the tools. These networks may use cookies or similar technologies to serve relevant ads and measure ad performance. You can control ad personalization through your browser settings or via Google's Ads Settings. Third-party vendors, including Google, may use cookies to serve ads based on a user's prior visits to this or other websites.

Links to other sites

Tool pages may link to other educational resources. This site is not responsible for the content or privacy practices of external sites.

Changes to this policy

This policy may be updated as the site adds features (such as an account system or premium tier) — check back periodically.
